Gastec Standard Tubes
Gastec standard tubes utilise colorimetric technology to perform spot sampling of around 300 hazardous and toxic gases, and chemical vapours in industrial environments.
Standard tubes provide a quick identification of gases. Fume hood confined space gas or COSHH assessments are among the most common uses.
You can also quickly search detector tube availability using our online stock check tool.
There are 10 tubes in a pack except for GAS31B (Oxygen). The standard tubes require an air sample to be drawn using the Gastec Sampling Pump (bought separately).
